Bitcoin Nears $80,000 After ETFs Post Their Best Week Since the Record Days of October

Bitcoin surged toward $80,000 on Monday, touching $79,954 in morning New York trading — up 25% in a week that has rewritten the year's narrative, after US exchange-traded funds recorded their best week since October, the month bitcoin set its $126,080 record.

Farside Investors data puts last week's ETF haul at $1.9 billion across funds run by BlackRock, Fidelity, Grayscale, Morgan Stanley, and peers — a violent reversal from the outflow grind that defined most of 2026, when the coin languished below $65,000 through a sluggish June and July.

Supply shock economics

Bloomberg Intelligence ETF analyst Eric Balchunas summarized the mechanics with characteristic economy, calling bitcoin "a commodity in a constant state of supply shock." The observation is arithmetic as much as rhetoric: with post-halving issuance near 450 coins a day, a $1.9 billion buying week at these prices absorbs multiples of new supply, and the difference has to come from existing holders — at whatever price convinces them to sell.

The catalyst chain runs through Washington: the Treasury's announcement that it would at least double its long-dated bond buybacks knocked the dollar and long yields lower, and the hard-asset complex — gold included — has been repricing ever since.

From despair to $80K in three weeks

What makes the move remarkable is the starting point. Three weeks ago the funds were bleeding, sentiment gauges read deep fear, and the consensus trade was AI equities. The speed of the reversal is itself the lesson: in an asset with inelastic supply and episodic demand, the transition from nobody-wants-it to nobody-will-sell-it does not take a quarter. It takes a headline and five trading days.
